IMPROVEMENT lN WEATHER-STRIPS.

Sp :cification forming part of Letters Patent No. 158,245, dated December 29, 1874; application filed October 31, 1874.

To all whom it may concern Be it known that 1, WILLIAM O. CHAMBER- LAIN, of Battle Ground, in the county of Tippecanoe and State of Indiana, have invented a new and useful Improvement in Weather- Strip for Doors, of which the following is a specification Figure l is a front view of the lower part of a door and door-frame, to which my improvement has been applied, taken from the inner side. Fig. 2 is a detail vertical section of the same, taken through the lineman, Fig. 1. Fig. 3 is a detail view of the same, taken from the outer side, and the door being shown as standing at right angles with the door-frame.

Similar letters of reference indicate corresponding parts.

My invention has for its object to furnish an improved weather-strip for doors, which shall be so constructed as to prevent the entrance of rain, snow, and wind; which shall be automatic in its action, and, at the same time, simple in construction, neat in appearance, durable, and not liable to get out of order.

The invention consists in an improved weather-strip for doors, formed of the two zinc strips, having their adjacent edges rolled to interlock with and turn upon each other, the two wooden strips, the spring, and the revolving guide-wheel, constructed and arranged to operate in connection with each other, as hereinafter fully described.

A represents the door-frame, B represents the door, and 0 represents the threshold, about the construction of which parts there is nothing new. D and E are two strips of zinc, of such a length as to reach across the door B, and the adjacent edges of which are curved or rolled so as to interlock with each other, and thus form a hinge extending entirely across the door B, the said rolls being so formed that water cannot enter between the rolls, and so that the said rolls may be readily slipped into each other endwise.

The free edge of the zinc plate D is secured to the lower part of the outer side of the door B by means of a strip of wood, F, which is secured to said door by screws or nails.

The free edge of the strip of zinc E issecured to a strip of wood, G, by nails or screws. H is a spiral spring, one end of which is attached to the stationary wooden strip F, and its other end is secured to the wooden strip G.

The elasticity of the spring H, when the strip G is free, raises the said strip G and supports it, so that it will pass over the threshold 0 without touching said threshold, when the door is swinging open and shut.

I is a small wheel pivoted to the lower part of the side post of the frame A, in such a position that when the door B is swinging shut the face of the said wheel I will. strike the wooden strip G and force its free edge downward, so as when the door is closed to be in close contact with the sill or base of the frame A, and thus prevent any entrance of rain, snow, and Wind. 7

The revolution of the wheel I as it comesin contact with the strip G prevents the said strip from being worn as it is forced down by the said wheel I in closing the door, and drawn out from beneath it in opening the door.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- 7 An improved weather-strip for doors, formed of the two zinc strips 1) E, having their adjacent edges rolled to interlock with and turn upon each other, the two wooden strips F G, the spring H, and the revolving guidewheel I, constructed and arranged to operate in connection with each other, substantially as herein shown and described.
